112 - Strange Physics of the Mind

Two fundamental theories -- quantum mechanics and relativity -- have changed forever our understanding of reality. Quantum mechanics describes the very small-scale structure of atoms and their components. Relativity describes the  very large-scale structure of space and time. Today's panelists discuss why some physicists have suddenly become obsessed with using physics to explain the human mind, consciousness and how we think. Joining host Robert Kuhn are sci-fi novelist Gregory Benford; physicist James Trefil; consciousness expert David Chalmers; philosopher of mind John Searle; and theoretical physicist Fred Alan Wolf.
